- rewrite of the logical sector handling code to make seek latency support possible
- implemented variable HD seek latency for seek and read commands
- TODO #1: CD-ROM seek command returns status immediately, but it clears the DSC bit
and sets it at completion. Device should not accept ATAPI commands until DSC is set.
- TODO #2: clean up the seek latency code
- temporarily disabled seek latency support for ATAPI command 0x2b until the
seeking status is implemented correctly
- fix for the MSVC compilation fix (result was always 0.0)
is almost a port of the Qemu 1.1.2 implementation. It has been tested successfully
on Linux and Windows (MinGW/MSYS). The networking module is currently called
"slirp_new", since the "slirp" backend module still exists.
TODO list:
- MSVC support (requires container_of() macro replacement)
- apply fixes and improvements from recent Qemu releases
- use our TFTP implementation to reduce code duplication
- check if we can share ARP and DHCP support with "vnet"
- add SMB support on Linux
- finally remove the slirp backend module support
- now using the more accurate name "seek latency"
- fixed CD-ROM LBA address range checks and renamed limit to "max_lba"
- make the latency for CD-ROM access variable depending on the distance between
current and new block address, Maximum value should only occur at first access
or after media change.
- TODO: make hard disk seek timing variable, too.
- still TODO: seek latency for USB drives (requires asynchronus packet support).
- some fixes for compiling with Cygwin
- enabled compilation of new slirp module in MinGW/MSYS and Cygwin
- TODO: slirp slows down Bochs emulation on Windows (Linux version is okay)
